Added a new utility zbinfo to query built-in data. This was released as an example previously (the dumplocale example which has been dropped).

Added encoding support to convert Wide_String values to String based on an encoding schema, e.g., UTF-8, ISO8859-2, CP932, SHIFT_JIS, etc. To fully use this functionality, narrow accessors should be used which, when printing, use Stream_IO to avoid interaction between the Text_IO and encoded values. The list of supported encodings is available via zbinfo --list-encodings.

The default locale is now en_US.UTF-8 if no other locale can be determined from the environment.

Updated the documentation (and website) to use the Sphinx documentation system.

Updated and expanded the documentation. Additional documentation is, however, needed. Switch to gnatdoc from gnathtml to generate the source code based documentation.

Restricted the usage of the -gnatW8 compilation option to just the source files containing UTF-8 encoded strings: the message pool file generated by the zbmcompile utility.
